Flea bites are tiny dark spots that mostly form on the feet and lower legs. After suffering several flea bites, some people get an allergic sensitivity to the affected area which ends up as an itchy rash or eczema.
Flea bites usually appear as small red spots or bumps after a person is bitten by a flea. These spots can be very irritating and itchy owing to the enzymes that the flea produces as it sucks blood. Most flea bites usually last a few hours in some people but other people may have serious allergies to flea bites.
